7-Duramax Marine DuraCooler Keel Cooler

• 90/10 cupro-nickel tubing is resistant to waterflow erosion and serves as an antifoulant.
• Compact, one-piece design makes installation simple.
• Streamlined header design reduces pressure drop in water flowing through the cooler. External water travels more quickly to tubes increasing the heat transfer efficiency of the cooler.
• Custom-sized for your engine specifications and operational requirements.
• Available with through-hull type fittings or non-through-hull flanges.

Don’t buy these coolers, there are companies who bought many of Duramax keel coolers and they won’t help you at all, this company Duramax will take your money and run. They have defect keel coolers, I would rather do business with other companies.
